There is a white webbing (similiar to spider webbing) on the top of my gardenia plant. Some of the leaves are turning yellow with brown spots, but there is a lot of new growth with new buds. What causes the white webbing and the leaves to turn yellow? What do I use and how to fix the problem? The plants are still in the original pots. I take them outdoors (south facing) during day and bring them in during night.

The webbing may be an indication of spider mites, which can be treated with neem oil.
